For the prototypes, we wanted walnut wood, but darker. We also wanted the walnut to not fade, as walnut does over time. Still, we wanted the finish to feel natural (oil), and not be a lacquer-type finish. The demand for the correct wood and finish was changed several times. Finally, we applied Aniline Dye Stain to walnut wood, actually dying the wood, and then applied a clear Danish Oil on the top.
